As a recent big acquisition by the Department of Education (ED) for IT services shows, GAO takes the integrity of the procurement system very seriously. The case sheds light on how agencies and contractors should respond when they believe the integrity of the procurement process may be threatened. Specifically, contractors may need to self-report breaches of the integrity rules, affected competitors need to act promptly to preserve their rights, and agencies must investigate problems and take appropriate action to ensure a fair procurement.
